The amount of money Emma receives in this scenario is £35.
<h3>What is Ratio?</h3>
This is defined as a comparison of numbers that indicates their sizes in relation to each other.
Helen and Emma = 2 : 5
2 = 5
x = x+21
We then cross multiply
5x = 2 ( x+21)
5x = 2x + 42
5x - 2x = 42
3x = 42
x = 42/3 = 14
Emma received x+21
= 14+21 = £35
